Add cruise control to S-Series?
I've been looking at used Saturns, especially the SW2. Many of them are great,
but don't have cruise control. Is it practical to add it? What's needed, and how much do the parts cost? Matt O. |

I did the audiovox JC whitney thing. Worked, but was a pain. Had to mount
the thing inside, activating gas pedal, as no adequate way under hood. Had to bring vacuum inside to make it work; would buy non-vacuum model if I had to do again. "C. E.

Electrical/electronic stuff is just so much more reliable, and vacuum leaks are a real PITA. Actually, I was hoping to find a factory-parts solution. You can install factory cruise control in a BMW pretty easily, so I'm wondering about Saturn too. Matt O. |

I added the vacuum type to my car and it works ok. As soon as the road
starts heading up the car slows and won't kick down unless I stomp on the gas myself. Once it has kicked down the car will climb back to the set speed without my foot on the gas and once the road flattens out it will shift back up again. I don't know if the electric ones have the same issue, but it's much better than nothing. |

It slows down most likely because the engine manifold vacuum is diminishing
under load. That is, assuming that all the linkages were properly tightened. Many cars with vacuum operated SC used a combination of manifold vacuum and ported vacuum (from the venturi of the throttle body). The ported vacuum is zero at idle but increases with engine load. Not the same if an electric one is used. "micven55" > wrote in message lkaboutautos.com... >I added the vacuum type to my car and it works ok.
